Cannot cast screen to LG TV - Xiaomi Mi 9 SE Questions & Answers

Hi all!
I have a long-standing problem with my Xiaomi Mi 9 SE: I have never been able to cast the screen of my phone to my LG smart TV.
The TV supports the functionality and the phone did show the TV in the list of available devices, but it would always abort with an error (on the phone).
Now I am not even able to try, as the phone does not show the TV anymore, in the list of available devices.
Anybody else experiencing this problem?
Thank you in advance

[Q] Galaxy S4 Mini (GT-I9195) and SCREEN MIRROIRNG with TV 3D Samsung UE40F6800SD

Hi to all,
i've this problem:
I tried to connect my Galaxy S4 mini to my Smart TV (Samsung UE40F6800SD), but when the two devices connect, after about 7-8 seconds automatically disconnect yourself (the image of the phone is never projected on the TV) . This happened while with firmware XXUAMF6. Yesterday I tried to update both the phone (with firmware XXUAMG8) that the TV (firmware 1110), but when I launched the screen mirroring the two devices were no longer visible.
Have you any idea what could be the problem?
Thank you very much.

Hi,
before to scan with youre phone, have you select on your TV ->source -> screen mirroring ?
1. set TV to "screen mirroring" (push "source" on remote)
2. enable phone menu "screen mirroring" then it should seek for tv and then allow devices to connect with each other.
PS! On my Samsung F6670 smart-tv the function didn't worked anymore after rooting (it did found the tv but disconnected immediately after showing succesful connection) though it worked fine before rooting.

So the problem is the root?!?!?!
OOPs I think only the F series has screen mirroring .....my Samsung UE46ES6800 is not supported probably....can't see this option

Sorry, my TV is UE40F6800SD
I think the screen mirroring is done through miracast (Samsung calls it AllShare Cast) and apparently it doesn't work with "some" rooted phones:
http://goo.gl/XahGnC
As for tv support, I couldn't find the ES6800 in the miracast ready devices.
http://www.wi-fi.org/wi-fi-certified-miracastâ„¢
The information is pretty scarce but I found this:
http://goo.gl/cvzcVp
"All Share": offers mirror modes between the TV, mobile phones and tablets.
Like in Philips TVs, Miracast Wi-Fi will be present in almost all Samsung's new models (from series 5 upwards)...

[Q] Miracast - Who has it working?

I have the fire stick, and can't get miracast to work. For those of you that do have it working, can you share your setup?
Devices I've tried:
Moto G with Lollipop
Surface Pro 3
HP Stream 7
Nokia Lumia 1520
For me it just sits on the waiting screen, sometimes my device name shows up saying mirroring will start soon but then it eventually times out and goes back to the settings screen.

I haven't been able to get Miracast on my Fire TV Stick to connect to me Windows 8.1 laptop.
Yes, I've gone to settings->display & sounds->enable display mirroring.
The first time I tried it on the laptop, it showed up in my devices (as a cell phone, which is strange), but when I "projected the screen", nothing ever showed up on the screen and it changed my laptop's resolution. I deleted it from devices and tried again and I can't get it to connect now. It just said said display mirroring is starting soon on the fire tv stick and just times out on the laptop.
On my LG G3, it didn't work last night, but when I tried it again just now, it worked.
Should the Fire TV Stick be able to Miracast with my laptop? My WLAN card does not support 5GHz. Is that the problem? The Fire TV Stick and LG G3 are connected via 5GHz, the laptop is connected to the same router via 2.4GHz.
I also can't get it to work with either my Lenovo X1 Carbon or, Samsung Series 7 tablet (Win 8.1 on both, miracast on the first, Intel WIDI on the second), the firetv is detected but it just won't connect. It worked with my Moto X, so I'm assuming it might just be working with android devices at this point which is a damn shame since this was one of the main selling points of the Fire TV stick for me.
Got it working on my Fire Stick and Nexus 5 running on custom kitkat rom. Had no luck on the first few try, my phone can see my fire stick and when it said it's connecting, the fire tv stick also said it's "preparing" to connect to my android device with my device name on the screen, but it would just disconnect without doing anything and go back to the setting screen after a few seconds.
Then i tried to turn off and turn on my wifi on my phone, tried again, fire tv now put the tv screen into a black & blank screen, but nothing more, it would disconnect again after a few seconds later. Tried a few times later on, same result, and no luck.
Again, i turn off my wifi on my phone and tried again and it now connected wonderfully! Tried youtube video on my phone and it's watchable on the tv, i'm going to try out a local video tomorrow and see how does it perform, so far i'm happy with browsing my photo in my phone alone without lags i found unacceptable on chromecast (but to be fair, it's not build for direct mirroring a device)
I have no luck in setting it up with my win 8.1 DELL e6540 laptop yet, i'm not sure if it even support miracast, would look into that also tomorrow. Right now i'm just happy it works on my phone and the quality is definitely acceptable.:good:
Hope it helps someone to setup your miracast!

3 of the 4 devices you try to cast are Windows, which you will expect problems since this is an Android system. The Moto G might have to deal with Lollipop and Google locking down Miracast for Chromecast only. I have a Nexus 7 and Nexus 9 on Lollipop and both can't cast to Amazon Fire TV. However, my Oneplus One and Galaxy Tab Pro 12.2 running CM11 can cast both to Chromecast and Fire TV/Fire Stick. I think this is due to some kind of ROM blocking. Just wait till somebody find a way around it. Most devs are busy porting Lollipop to old Android devices.

That's probably the case, I just thought being Miracast certified meant it was actually supposed to work.
I've both a Note 3 and a LG G3 but can't miracast to my fire tv device from either. The phones can seethe fire tv and their name appears briefly on screen but then it simply fails. Everything is unrooted.

no luck on my nexus 5 with lollipop. stays on the connecting screen and then just stops trying to connect.
Works for about a minute and then stops
Stock Nexus 5 running Lollipop. Activated casting on the Fire Stick, and then on the N5. It seems like I had to get off of the cast screen on the N5 before it would start casting. I simply went back to the home screen. Tried to cast a you tube video which worked for a minute or so but then the TV screen went blank. Eventually the Fire Stick said the connection was dropped.
From what I've seen, it looks as though Google silently dropped Miracast support in Lollipop. The option to cast your screen from the OS appears to only work with the chromecast protocol now. They also broke car mode... Again. ?
I have it sort of working with Moto X KitKat - I can mirror the phone, but if I try to stream a Google Play movie it stutters and hangs. I could be my wifi signal - I have not tried it elsewhere in the house, but that is my next step.

I have the same symptoms - my LG G2 running Cyanogenmod 11 (4.4.4) can usually mirror fine to my Fire TV Stick, but sometimes it can't connect - a power cycle on the Fire Stick makes it work again.
However, my Windows 8.1 Pro x64 Surface Pro (1) can't establish a connection. After pressing the Add Wireless Display button, the Fire Stick is detected as a "Cell Phone." (That's probably indicative of the problem?) Then, attempting to connect to the FTVS results in the stick saying "a connection will start soon to "MYSURFACEPRO" for a few seconds, then the Fire TV Stick dumps back out to the Settings menu. Windows waits for a minute or so and eventually gives an error message.
I ran Windows Update and rebooted, but had same non-result.
I don't think Windows is detecting the Fire TV Stick as a "Wireless Display", so maybe that's why the FTVS is aborting the connection - Windows is negotiating wrong????

Same here. Does not miracast windows displays.
Miracast is such a bull**** standard. How can they certify devicess when they all have different handshake procedures.
Im hopping for an update. I tried with three laptops.
works for me on a stock att galaxy s5 no issues, even video streams from showbox work well. no luck with custom rom note2. looks like its too old for miracast, but streambles app works alright and no sideload needed since its on amazon fire tv app store.
With Fire Stick, works with Galaxy Tab s 8.4, not so much with Verizon S5 or Note 3.
Galaxy S3; CyanogenMod 11 = Successful screen cast but no audio (is audio supposed to work).
Galaxy S4 Stock KitKat = Successful screen sharing, but again no audio.
Kindle Fire HD 7" (2012 version). CyanogenMod 11 = Fail (Screen cast seems disabled on this device with current builds of CM11)
Lenovo Miix 2 11 with Windows 8.1 = Fail (same problems as everybody else)
Dell XPS 12 with Windows 8.1 = Fail (ditto)
Intel NUC ( D54250WYK ) with Windows 8.1 = Fail (broken record)
All attempts to share screen with my Fire TV Stick on current (as of 12/15/14) firmware.

Good point - my audio didn't work either with my LG G2 VS980 running CyanogenMod 11. Forgot about that part of it. And yes, audio is definitely supposed to work.

Can't connect my Note 8 to my Samsung TV

Hi, can anyone help me. Before I put the CM 12 on my Note 8 I could connect it to my TV via Screen mirroring easily.
Now I have the possibility in the settings, but it cant find the TV.
As before both are in the same WIFI network.
I can do this with my Sony unrooted device as i could do it before.
Does someone have the right .apk or an Idea how to fix it.
I like to have just the display of the tablet on my TV nothing else.
The Samsung app from the playstore doesnt work.
Thanks Chris

Howt cast N5x to TV

Has anyone tried to cast their Nexus 5x to the TV without using any kind of electronic device like chromecast and etc. but by just using the phone itself? If so, can someone help me out. I've tried many ways but it seems like my phone doesn't recognize my LED TV. It always says "No nearby devices were found".
Sorry for double posting. Please delete this. Thanks!
it happen only Nougat when i was on marshmallow its works fineT^T
Mine is the same, worked in my Nexus 4 but Google seem to have disabled it in the 5X and it's a pain as we used to show photos on the TV screen instead of passing g around my phone. I've yet to find a solution
I tried miracast and it doesn't work to me either ..
So +1
Google killed Miracast in Android N.

Since the casting function is specifically made for chrome cast it won't work without it.
On the bright side, a chrome cast device is really cheap and will work with any device that can run chrome or chromium.
Just having a LED TV doesn't mean anything, is it a smart TV and if so what OS is it running?

Screen casting a MI A2 Lite to a Sony Bravia Smart TV - Not working

Hello everyone!
I'm trying to screen-mirror my A2 Lite to a Smart TV Sony Bravia KDL40W605B, but for the moment I cannot do it.
Both the devices are connected to the same wireless network, they browse happily without any problem and have the latest software updates installed.
If I choose "Cast" from the notification bar and choose the Sony Bravia TV from the device list, nothing happens.
What am I doing wrong? Is there any way to solve this issue?
Thanks to whomever will answer me.
P.S. Just for saying, my old Samsung A3 (2015) and my old Huawei P8Lite (2016) did screen mirroring with that Sony TV without any problem.

I don't think there is a solution yet, except trying some 3rd party apps. I also tried to use this phone with screen mirroring or whatever Samsung TV's function is called, and it briefly worked, the image freezed on the tv, followed by the phone failure to connect to that device again until unplugged and plugged in again, followed by the same error. Sometimes it would work for hours, sometimes not at all.
On my friends Samsung (A5 or something like that) connecting to that TV works just like charm.

Hello TheoXSD, thanks for answerring me.
If the built-in "Cast" software doesn't work, then I'll use third party apps, there's no problem for me. The question is: which app should I use? I searched a bit on google play store and found tons of applications regarding this topic, but the majority looked quite obsure and strange to me...
My goal is to just duplicate my smartphone screen into my Bravia TV, nothing more.
Can't really understand why Samsung decives work so well when casting the screen...

I really have no idea. Better software support and licensing I presume.
As for which app to use, I have no idea, check them one by one, which fits you best. I gave up on screen mirroring since that day.

I understand. May I ask once again if anybody has any solution to this problem?
Because maybe I am doing something wrong, without knowing it.
That's just it, I choose "Cast" from the status bar, it recognises the Bravia TV and then...nothing happens and it loads forever.
Please somebody help

I guess the only problem would be that I need to screen cast my smartphone's screen through wireless and not through cable. Thanks anyway.
However, yesterday something happened, both positively and negatively and I managed to cast my Mi Xiaomi Mi A2 Lite to my Sony Bravia KDL40W605B.
I followed a tutorial on YouTube by Geeki Review and it worked once, just once, perfectly, and then it stopped and I couldn't manage to make it work again ever more, even though I replicated the same exact steps.
The tutorial was like this:
1) Go to TV -> System Settings -> Setup -> WiFi Setup (Or simply go to SEN, Settings, Network).
2) Activate WiFi and WiFi Direct and then go to WiFi Settings
3) Press Options on the remote and choose Manual, Other method, No WPS
4) Now the TV offers you a WPA Key, take a picture of it or write it somewhere!
5) On your smartphone go to Settings, turn of the WiFi, find the Bravia Wifi network and connect it using the WPA Key
6) Wait untile the registration process completes and the choose to forget that WiFi Network
7) Now on the TV remote go to Soucres and choose Screen mirroring
8) On your smartphone choose Cast from the notification bar, choose Bravia TV, choose Accept on the TV and then wait, it may take some minutes.
It worked perfectly only ONCE.
